Why Does the Compressor of a Low-Temperature Test Chamber Fail to Start?

The compressor is a critical component of a low-temperature test chamber. Why does it sometimes fail to start? What aspects should we check?

The troubleshooting process for a low-temperature test chamber compressor that fails to start should begin with an electrical circuit inspection. First, check if there is an issue with the motor circuit connection. If the problem lies in the equipment’s circuit, inspect the motor circuit connection points to determine if poor connections are the cause. Immediate fault diagnosis and repair are necessary.

Additionally, check if the power supply voltage is too low. If the grid voltage is insufficient, wait for it to return to normal levels before attempting to start the compressor.

Another factor to consider is whether the exhaust valve is leaking. If the exhaust valve is damaged or improperly sealed, it can cause excessive pressure in the crankcase, preventing the compressor from starting. In this case, the exhaust valve and sealing components need to be replaced.

Malfunctions in the energy regulation mechanism can also cause the compressor to fail to start. This requires checking the oil supply pipeline for blockages, low pressure, or stuck oil pistons. If any faults are detected, they should be addressed promptly.

Pressure relays and temperature controllers should also be inspected. If the issue lies with the pressure relay, the set pressure parameters may need adjustment. If the temperature controller is malfunctioning, it should be recalibrated or replaced if damaged. In such cases, it is advisable to contact the manufacturer’s technical support for repair or replacement.
